The Very Best of the #ALSIceBucketChallenge: Celebrity Edition

The ALS Ice Bucket Challenge has officially jumped off your Facebook newsfeed into Hollywood, and I can't think of a better way to deal with a Monday than by watching celebrities dump ice water on themselves and scream...all in the name of raising awareness for Lou Gehrig's disease, of course.

The vides have raised $15.6 million in donations since July 29, according to the ALS Association national office—and I can only imagine the star-power behind these videos will keep that number rising. But, hey, if you're gonna laugh at them, you better do your part by uploading your own video and donating to ALS now.

Jennifer Lopez

JLo combined workout and philanthropy in her ALS vid; she took advantage of yesterday's beautiful weather to get dunked outside—after a workout with cardio queen and unofficial Hollywood workout guru Tracy Anderson, then challenged her musical collaborators, Iggy Azalea and Pitbull, to get soaked, too.

Lena Dunham

The Girls creator debuted a brand-new platinum blonde bob (and featured a cameo from her adorable pup Lamby) while soaking herself in the name of charity. Your move, Marn.

Taylor Swift & Jaime King

Never one to be without a BFF, #ShakeItOff songstress Swift enlisted King for a double dunk in front of a major group of onlookers/fans. They also waved some hundreds around, and announced they'd be donating them on behalf of every person in the crowd. So charitable, that one.

Underwood and her hockey-playing husband went country, enlisting an actual tractor to dump water on them. I guess "bucket" means something different to everyone.

Emmy Rossum

Um, Rossum's got some guns on her—that heavy bucket is no joke. Also, her reaction is adorable hilarious and her bathing suit is awesome. Well played, Emmy.

Justin Timberlake

Because, yes. Why wouldn't we want to see a dripping wet Justin Timberlake?

Lady Gaga

In true form, a Goth-dressed Gaga turned her Ice Bucket Challenge into art, with slo-mo lifting and a deadpan facial expression (any nary a smear of her black lipstick).

Kerry Washington

Not the Prada, Olivia! Washington soaked herself on the set of Scandal on behalf of the show's entire cast. That Olivia Pope, always willing to take one for the team. (PS: Who's excited to shop Pope's style?)

Bill Gates

Genius Bill Gates really upped the ante on this one, building his on self-soaking contraption and putting the rest of these celebs to shame. I mean, if there was ever a time to throw your millions of dollars around...

Elizabeth Banks

The actress went the safe route, dumping water on herself in the shower. Kudos for at least doing it in your real clothes and not a bathing suit, Banks!

Selena Gomez

Gomez was nominated by Swift and Ryan Seacrest, and happily met the challenge—and I love that she used what looks like a drawer from my plastic dorm room storage container.

Oprah

It's not a movement until O weighs in, and weigh in she did this weekend, enlisting the help of her BFF, Gayle King. Her reaction is epic. If Oprah can do it, you have no excuse.

Nina Dobrev

The Let's Be Cops and Vampire Diaries star didn't waste any time in her video—she stripped off her shirt, said "Let's do it," and got doused, even using a nifty slo-mo effect. Then she jumped off her yacht into the ocean. As one does.
